CAR SIGNALING SYSTEM.

7 T 0 all whom it may concern:

Be it known that I, WILLIAM H. IIEUL- INGS, J r., a citizen of the United States, and a resident of the cityand county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Car Signaling Systems, of which the followingis.

a specification.

The object of my invention is to provide a suitable device for closing an electric circuit whereby a signal may be sounded in a street car. This, and other objects, are accomplished by my invention, one embodiment of Which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which- Figure 1 is an interior view of the upper portion of a car containing my improvements, parts being shown in section to more clearly reveal the structure; Fig. 2 is a sectional view, taken substantially on the line 2-2 of Fig. 1., looking in the direction of the arrows; Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2, looking in the direction of the arrows; Fig. 4 is a sectional view, taken on the line 44 of Fig. 1, looking in the direction of the arrows; and Fig. 5 is a sectional view, taken substantially on the line 5-5 of Fig. 1, looking in the direc tion of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts.

Myimproved circuit closer 1 is particularlyadapted for metal cars where a single wire is used, the circuit being closed by grounding the wire whenever a signal is given. In the preferred embodiment of my invention the wire or other conductor 2 is passed through a metal conduit or tube 2 which at each post is out to allow of the insertion of a junction box 3 at the bottom of which is mounted a suitable plunger 4 which can be moved in the direction of its length. This plunger 4 is preferably mounted in a suitable bracket 5 with a perforation in its upper extremity adapted to receive this plunger and form a guide for same, the bracket at the same time serving as a closure for the open bottom of junction box 3. This bracket 5 also has a transversely extending perforation in which is mounted a suitable pivot 6 which carries a bell crank lever 7 Specification of Letters Patent.

with one arm 8 adapted to rest under the plunger 4, and a secondarm 9 which is adapted to swing against the toe 10 of a lever 11, which is provided with suitable ears 12 placed on each side of a suitable stanchion 13 and pivotally connected thereto by means of a pivot 14. The lower end of the lever 11 is pressed outwardly by a suitable coil spring 15, which rests against this lever and also against the stanchion 13 and forces the lower end of the lever against a suitable push button '16, which is mounted in the lining 17 substantially as shown, or in any suitable manner. Within the junction box 3 is mounted a contact maker or switch of any suitable construction, and in order to avoid the cutting of the conductor 2, I remove the insulation therefrom for a short distance and clamp the bared portion of the conductor under one of the terminals of the switch; the other terminal or pole of the switch is connected to the junction box by a screw or other suitable means so that the junction box and conduit will form the return circuit. It will be understood that the switch is closed by the upward movement of the plunger 4.

In view of the foregoing, the operation of my device will be readily understood. when the push button 16 is pressed against the lower end of the lever 11, the toe of this lever presses against the weighted end 9 of the bell crank lever 7 and forces the other end 8 of this lever against the plunger 4 and elevates the same until it closes the switch and thereby completes an electric circuit through the signal of the car.

It is apparent from the foregoing that my improved circuit closing device may be actuated without the least danger of causing a shock to a passenger when pressing the button 16. It is preferable to make this button 16 of some insulating material such as vulcanite,'but it may be made of metal or anything else, as no electricity can, in any event, pass through it.

While I have shown and described one e1nbodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures which come within the scope of the annexed claims.

Having thus described my invention, what I claim is:

1. In a device of the class described, a bare conductor mounted in a junction box,

a plunger supported by said junction box anda push button and levers to actuate said plunger to cause it to contact With the bare conductor and close the circuit.

2. In a device of the class described, a bare.

conductor, a plunger mounted below said conductor, a bell cranlrlever pivoted below said plunger, a lever hinged on a car post,

a push button engaging the lower end of said lever, the upper end of said lever enovaging (the bell cranklever and causing said belllcr'ank lever to raise'the plunger against the conductor.

3. In a device ofthe class described, a

bare conductor mounted in a junction box, 15

a bracket under said junction box With a plunger mounted at the upper end thereof and adapted to engage said bare conductor when raised, a bell crank lever pivotally mounted in said bracket With one end under 20 Signed at the city and county ofPhiladel- 25 phia, and State of Pennsylvania, this 9th day offJune, 1915'.
